Definitions

  • the present invention relates to a pump or pumping assembly, arrangement or combination; and more particularly relates to a pump or pumping assembly, arrangement or combination designed for installation conversion, e.g., for a centrifugal pump, a slurry-type pump, as well as other types or kinds of rotary equipment such as fans or compressors.

  • Figure 1 b shows another known pump design generally indicated as 20 also having its adjusting screw 22 arranged in a base 23 under a bearing cartridge generally indicated by arrow 24 having a power transmitting shaft 27 arranged therein, the adjusting screw 22 configured for adjusting, e.g., the clearance of an impeller 26 coupled to the shaft 27 arranged in a pump shell 28.
  • Figure 1 c shows still another known design generally indicated as 30 also having its adjusting screw arrangement generally indicated by arrow 32 arranged in a base 33 underneath a bearing assembly generally indicated by arrow 34 having a power transmitting shaft 37 coupled to an impeller 36 arranged therein, the adjusting screw arrangement 32 configured for adjusting the relationship between the bearing cartridge 34, impeller 36 and a pump shell 38.
  • the bearing cartridge may be configured to be coupled to a pumping assembly combination and having a predetermined centerline.
  • the pedestal may be configured with an axial channel to receive and support the bearing cartridge and allow the bearing cartridge to slide therein.
  • the bearing cartridge and the pedestal are configured to couple together substantially at or above the centerline of the bearing cartridge in order to reduce center height requirements of the apparatus, where the center height is defined as the distance between the centerline of the bearing cartridge and the bottom surface of the pedestal supporting the bearing cartridge.
  • the apparatus takes the form of a pump or pumping assembly, arrangement or combination, including a slurry-type pump or a centrifugal pump.
  • the apparatus may also include one or more of the following features:
  • the bearing cartridge and the pedestal are configured to couple together by an adjustable mounting assembly.
  • the adjustable mounting assembly may include, e.g., at least one mounting member coupled to the pedestal; at least one corresponding mounting member coupled to the bearing cartridge; and an arrangement of threaded bolts or rods and nuts configured to couple the at least one mounting member of the pedestal and at least one corresponding mounting member of the bearing cartridge so as to slide the bearing cartridge in relation to the pedestal when one or more of the nuts is turned.
  • the apparatus may also include a base adapter configured to be arranged between the pedestal and a pre-existing supporting foundation and to support the pedestal on the pre-existing supporting foundation.
  • One advantage of the new design or technique is that it offers users the ability to completely replace an existing pump without disturbing the original foundation or suction/discharge piping (depending on user preference). The user can then benefit from improvements in a bearing cartridge or assembly design as well as
  • An additional advantage is afforded to the manufacturer as a pump with a low center height and corresponding foundation cannot be replaced by competitors, requiring new foundations and dissuading customers from replacing the piece of equipment.
  • the new design or technique consists of a pump with a wet end and a powerframe (also called a bearing frame or power end).
  • the powerframe has a center to base height very near the minimum achievable with current materials technology, significantly less than current offerings. This allows for cast, fabricated, or machined spacers to be put between the powerframe of the new pump and the existing foundation to allow the adjustment of the new pump's center height and position relative to drive elements (motor and gearbox shafts) and suction or discharge piping. Different spacers can be provided to allow a single model of pump to be adapted to multiple models of competitor equipment.

Abstract

Cette invention concerne un appareil comprenant une cartouche de palier associée à un socle. La cartouche de palier peut être conçue pour être accouplée à une combinaison de type ensemble pompe et ayant un axe médian prédéterminé. Le socle peut être pourvu d'une rainure axiale destinée à recevoir et à supporter la cartouche de palier et à permettre son coulissement dans ladite rainure. La cartouche de palier et le socle sont conçus pour s'accoupler sensiblement sur ou au-dessus de l'axe médian afin de réduire les exigences de hauteur centrale, la hauteur centrale étant définie comme la distance entre l'axe médian de la cartouche de palier et la surface inférieure du socle supportant la cartouche de palier. L'appareil adopte la forme d'une pompe ou d'un ensemble, agencement ou combinaison de pompes, comprenant une pompe de type à boue ou une pompe centrifuge.
